Internal mechanical failure of XX lever

The front lever on my XX brakes has failed after only 1 year of use. When attempting to bleed the front brake the brake fluid will not flow from the lower caliper plunger into the upper lever plunger as it is supposed to do. There is some blockage in the lever. I removed the hose from the lever and fluid flows fine, so itís in the lever. When I reassemble the brake the lever pulls all the way to the handlebar, so it basically no good. I have not crashed with this lever or in any way abused it. I bled the thing on a regular basis. I did everything right and it still failed. This is unacceptable for a produce that cost so much and represents the top-of-the line of Avid brakes. Do not buy these brakes.
